Introduction This booklet summarizes the Hanford Site Environmental Report for Calendar Year 2001. The report includes information and summary data that describe environmental management performance at the site, demonstrate the status of the site’s compliance with applicable federal, state, and local environmental laws and regulations, and highlight significant environmental monitoring and surveillance programs and efforts. The document is written to meet requirements and guidelines of the U.S. Department of Energy (DOE) and the needs of the public. This summary booklet is designed to briefly 1) describe the Hanford Site and its mission; 2) describe environmental programs at the Hanford Site; 3) discuss estimated radionuclide exposures to the public from 2001 Hanford Site activities; 4) summarize the status of compliance with the site’s environmental regulations; and 5) present information on environmental monitoring and surveillance and groundwater protection and monitoring. Readers interested in more detailed information can consult the 2001 report or the technical documents cited and listed in that report. 1 The 300 Area

  • Excerpt from the Yakima Nation/Cleanup of Hanford
    DOE Indian Policy and Treaty Obligations Excerpt from The Yakama Nation and the Cleanup of Hanford: Contested Meanings of Environmental Remediation written by Daniel A. Bush (2014) http://nativecases.evergreen.edu/collection/cases/the-yakama-nation-and-the-cleanup- of-hanford-contested-meanings-of-environmental-remediation Map: Yakama Reservation and lands ceded by the Yakama in the 1855 treaty (Klickitat Library Images, 2014) According to the DOE’s Tribal Program, “the involvement [of] Native American Tribes at Hanford is guided by DOE's American Indian Policy [which] states that it is the trust responsibility of the United States to protect tribal sovereignty and self-determination, tribal lands, assets, resources, and treaty and other federal recognized and reserved rights” (Department of Energy (DOE) Tribal Program, 2014). Therefore, where Native Americans are concerned it would seem that the DOE has a legal obligation to restore the Hanford site to its pre-nuclear state. It could also be argued that Native tribes have their own trust responsibility for preservation of natural resources on both tribal lands and those areas of traditional use. Moreover, the web of responsibilities associated with the Hanford cleanup are complicated by potential liabilities, as Native peoples have a right to “damages for injuries which occur to natural resources as a result of hazardous waste release” (Bauer, 1994). Thus, Native Americans who traditionally used the affected area have also been involved in the cleanup of Hanford. CERCLA itself named Native tribes as having a vested interest in Superfund sites such as Hanford. The DOE agrees that the Nez Perce Tribe, the Confederated Tribes of the Umatilla Indian Reservation, the Confederated Tribes and Bands of the Yakama Indian Nation, and Wanapum native peoples be regularly consulted throughout the cleanup process and that all have rights to resources in the 1 Hanford region.

    1999 Evaluation of Juvenile Fall Chinook Salmon Stranding on the Hanford Reach of the Columbia River DRAFT Prepared for The Bonneville Power Administration The Public Utility District Number 2 of Grant County John Nugent Todd Newsome Wendy Brock Mike Nugent Paul Hoffarth Paul Wagner Washington Department of Fish and Wildlife December 7, 2001 BPA Contract Number 9701400 GCPUD Contracts Document 97BI30417 Executive Summary The Washington Department of Fish and Wildlife (WDFW) in cooperation with the Bonneville Power Administration (BPA), Grant County Public Utility District (GCPUD), Pacific Northwest National Laboratory (PNNL), University of Idaho (U of I), Streamside Programs Consultation (SPC), United States Geological Survey Biological Resources Division (USGS/BRD), and Yakama Nation (YN) performed the 1999 Evaluation of Juvenile Fall Chinook Salmon (Oncorhynchus tshawytscha) Stranding on the Hanford Reach of the Columbia River. The 1999 evaluation was the third year of a multi-year study to assess the impacts of water fluctuations from Priest Rapids Dam on rearing juvenile fall chinook salmon, other fish species, and benthic macroinvertebrates. The field effort was performed from March 5 through September 29. The objectives of the 1999 evaluation were to collect basic information on the physical parameters of the Hanford Reach, evaluate the extent of stranding and entrapment of juvenile fall chinook salmon and other fish species, and identify critical habitat zones. The information will be used to develop a model for determining susceptibility of juvenile fall chinook salmon to stranding and entrapment due to flow fluctuations. WDFW subcontracted U of I and SPC to assess the effects of flow fluctuations on the benthic macroinvertebrate communities and USGS/BRD to study the effects of heat stress on the survival, predator avoidance ability, and physiology of juvenile fall chinook salmon.

  • Distribution of Juvenile Fall Chinook Salmon
    2001 Evaluation of Juvenile Fall Chinook Salmon Stranding on the Hanford Reach of the Columbia River Prepared for The Bonneville Power Administration The Public Utility District Number 2 of Grant County John Nugent Todd Newsome Paul Hoffarth Michael Nugent Wendy Brock Michael Kuklinski, Jr. Washington Department of Fish and Wildlife May 29, 2002 BPA Contract Number 9701400 GCPUD Contracts Document 97BI30417 Executive Summary The Washington Department of Fish and Wildlife (WDFW) in cooperation with the Bonneville Power Administration (BPA), Grant County Public Utility District (GCPUD), and Pacific Northwest National Laboratory (PNNL), performed the 2001 Evaluation of Juvenile Fall Chinook Salmon Stranding on the Hanford Reach of the Columbia River. The 2001 evaluation was the fifth year of a multi-year study to assess the impacts of water fluctuations from Priest Rapids Dam on rearing juvenile fall chinook salmon. The field effort was performed from March 14 through June 28. The objectives of the 2001 evaluation were to collect basic information on the physical parameters of the Hanford Reach, evaluate the extent of stranding and entrapment of juvenile fall chinook salmon and other fish species, and identify critical habitat zones. PNNL will use this information to develop a model for determining susceptibility of juvenile fall chinook salmon to stranding and entrapment due to flow fluctuations. The overall goal will be to develop a long term agreement for the protection of juvenile fall chinook during emergence and rearing. River and meteorological conditions on the Hanford Reach during the 2001 juvenile fall chinook salmon emergence and rearing period (March–July) were marked by below average river flows, above normal river temperatures, near normal ambient air temperatures, and below average solar radiation levels.
